Official Description

Tympanostomy (requiring insertion of ventilating tube), local or topical anesthesia

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The procedure described by CPT® Code 69433 involves a tympanostomy, which is a surgical intervention aimed at addressing issues related to the middle ear, specifically chronic otitis media and Eustachian tube dysfunction. Chronic otitis media refers to persistent inflammation or infection of the middle ear, while Eustachian tube dysfunction occurs when the Eustachian tube, a narrow passage connecting the middle ear to the back of the nose, fails to open and close properly. This dysfunction can lead to the trapping of air in the middle ear, resulting in negative pressure that can retract the tympanic membrane, commonly known as the eardrum. The procedure entails making a small incision in the tympanic membrane to allow for the removal of any accumulated fluid within the middle ear through suction aspiration. Following this, the Eustachian tube is opened by inflating it with air, which helps restore normal function. To maintain the opening created in the tympanic membrane, a ventilating tube is inserted. This procedure is performed under local or topical anesthesia, making it less invasive and allowing for quicker recovery compared to general anesthesia. It is important to note that if general anesthesia is required, CPT® Code 69436 should be used instead.

1. Indications

The tympanostomy procedure with the insertion of a ventilating tube, as described by CPT® Code 69433, is indicated for the following conditions:

  • Chronic Otitis Media - This condition involves persistent inflammation or infection of the middle ear, which can lead to fluid accumulation and hearing impairment.
  • Eustachian Tube Dysfunction - This occurs when the Eustachian tube does not function properly, leading to blocked airflow and pressure imbalance in the middle ear, resulting in fluid buildup.

2. Procedure

The tympanostomy procedure involves several key steps that are crucial for its success:

  • Step 1: Anesthesia Administration - The procedure begins with the administration of local or topical anesthesia to ensure patient comfort during the surgery. This type of anesthesia numbs the area around the ear, allowing the physician to perform the procedure without causing pain.
  • Step 2: Incision Creation - A small incision is made in the tympanic membrane (eardrum). This incision is necessary to access the middle ear and is performed with precision to minimize trauma to surrounding structures.
  • Step 3: Fluid Removal - Once the incision is made, any fluid that has accumulated in the middle ear is removed using suction aspiration. This step is critical as it alleviates pressure and helps restore normal ear function.
  • Step 4: Eustachian Tube Inflation - After the fluid is cleared, the Eustachian tube is opened by inflating it with air. This inflation helps to restore proper airflow and pressure regulation within the middle ear.
  • Step 5: Tube Insertion - Finally, a ventilating tube is inserted into the opening created in the tympanic membrane. This tube serves to maintain the opening, allowing for continuous drainage of fluid and equalization of pressure in the middle ear.

3. Post-Procedure

After the tympanostomy procedure, patients are typically monitored for a short period to ensure there are no immediate complications. Post-procedure care may include instructions on keeping the ear dry and avoiding water exposure to prevent infection. Patients may also be advised on signs of potential complications, such as increased pain, fever, or drainage from the ear, which should prompt a follow-up with their healthcare provider. Recovery is generally quick, and many patients experience an improvement in hearing and a reduction in ear-related symptoms shortly after the procedure.

50 Bilateral procedure: unless otherwise identified in the listings, bilateral procedures that are performed at the same session, should be identified by adding modifier 50 to the appropriate 5 digit code. note: this modifier should not be appended to designated "add-on" codes (see appendix d).
59 Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25.
51 Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d).
AQ Physician providing a service in an unlisted health professional shortage area (hpsa)
GA Waiver of liability statement issued as required by payer policy, individual case
22 Increased procedural services: when the work required to provide a service is substantially greater than typically required, it may be identified by adding modifier 22 to the usual procedure code. documentation must support the substantial additional work and the reason for the additional work (ie, increased intensity, time, technical difficulty of procedure, severity of patient's condition, physical and mental effort required). note: this modifier should not be appended to an e/m service.
52 Reduced services: under certain circumstances a service or procedure is partially reduced or eliminated at the discretion of the physician or other qualified health care professional. under these circumstances the service provided can be identified by its usual procedure number and the addition of modifier 52, signifying that the service is reduced. this provides a means of reporting reduced services without disturbing the identification of the basic service. note: for hospital outpatient reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well-being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
53 Discontinued procedure: under certain circumstances, the physician or other qualified health care professional may elect to terminate a surgical or diagnostic procedure. due to extenuating circumstances or those that threaten the well being of the patient, it may be necessary to indicate that a surgical or diagnostic procedure was started but discontinued. this circumstance may be reported by adding modifier 53 to the code reported by the individual for the discontinued procedure. note: this modifier is not used to report the elective cancellation of a procedure prior to the patient's anesthesia induction and/or surgical preparation in the operating suite. for outpatient hospital/ambulatory surgery center (asc) reporting of a previously scheduled procedure/service that is partially reduced or cancelled as a result of extenuating circumstances or those that threaten the well being of the patient prior to or after administration of anesthesia, see modifiers 73 and 74 (see modifiers approved for asc hospital outpatient use).
58 Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78.
74 Discontinued out-patient hospital/ambulatory surgery center (asc) procedure after administration of anesthesia: due to extenuating circumstances or those that threaten the well being of the patient, the physician may terminate a surgical or diagnostic procedure after the administration of anesthesia (local, regional block(s), general) or after the procedure was started (incision made, intubation started, scope inserted, etc). under these circumstances, the procedure started but terminated can be reported by its usual procedure number and the addition of modifier 74. note: the elective cancellation of a service prior to the administration of anesthesia and/or surgical preparation of the patient should not be reported. for physician reporting of a discontinued procedure, see modifier 53.
76 Repeat procedure or service by same physician or other qualified health care professional: it may be necessary to indicate that a procedure or service was repeated by the same physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 76 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
77 Repeat procedure by another physician or other qualified health care professional: it may be necessary to indicate that a basic procedure or service was repeated by another physician or other qualified health care professional subsequent to the original procedure or service. this circumstance may be reported by adding modifier 77 to the repeated procedure or service. note: this modifier should not be appended to an e/m service.
78 Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.)
79 Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.)
80 Assistant surgeon: surgical assistant services may be identified by adding modifier 80 to the usual procedure number(s).
